DefenseReview (DR) recently received a press release on the American Clandestine Equipment (ACE) SMG9-SC high-volume lightweight, full-auto-grade 9mm Parabellum/9x19mm NATO SMG (Submachine Gun) silencer/sound suppressor that they developed for the CZ Scorpion Evo A1 subgun and CZ Scorpion Evo 3 S1 SBR (Short Barelled Rifle). The ACE rep we spoke with told us that a suppressed CZ Scorpion Evo 3 A1 or S1 is not only a big deal, but a huge deal, since the Scorpion itself is so popular, and the suppressor aspect really optimizes it.
The Firearm Blog’s recent piece on the developmental “reflex-suppressed” CZ Scorpion reinforces the suppressed Scorpion’s importance. From CZ’s graphic, the “reflex-suppressed” Scorpion would appear to have a much shorter barrel than the recessed-suppressed Scorpion Evo 3 S1 pistol/SBR DR covered.
The graphic The Firearm Blog showed also featured an HB Industries aluminum handguard designed and developed specifically for that gun, and it looks good. Speaking of looking good, the ACE SMG9-SC muzzle can looks pretty good too, at least on paper.
DR’s been told that a shorter variant of the SMG9-SC suppressor will be available in a few weeks, as will a 3-lug mount version adapted for use on other hosts (guns). Defense Review looks forward to seeing that one, as well.
The following is the official press release on the ACE SMG9-SC Scorpion suppressor, including specs:
“The American Clandestine Equipment SMG9-SC is a light weight, large internal volume suppressor that is optimized for use with the CZ Scorpion Evo 3 S1/A1. The SMG9-SC is precision machined from fine quality materials with attention to detail craftsmanship and exacting quality controls. Quality construction combined with smart design features and outstanding sound level reduction results in this next level performing suppressor.
12 clipped ported baffle cones and large internal volume provides a measured sound level reduction of 32.5dB, bottoming out on the Scorpion’s chamber and action noise. 147grain 9mm ammunition with a muzzle velocity of 1025 feet per second ( 343 ft-lbs energy ) fired through an SMG9-SC equipped Scorpion meters at 117dB in the MIL-STD-1474D test and 127dB at the shooters ear. The baffle design also minimizes zero point shift to less than 2 MOA and first round pop is completely eliminated. Careful use of materials minimizes the weight while maintaining strength and durability. At 10.75 ounces the SMG9-SC is full auto rated to 90 rounds and 9mm+P capable.
An adjustable 1/2-28 threaded mount made specifically for the Scorpion utilizes the stock compensator catch providing a rigid mount that prevents loosening of the suppressor during movement or when firing. The mount indexes to exactly the same position each time it is installed. Once the sights are zeroed in with the suppressor installed, it can be removed and installed without subsequent adjustment of the sights for zero point shift. The mount cap is adjusted to fit the Scorpion the first time it is installed. After initial adjustment removal and installation of the suppressor is tool free.
The serialized ring component is separate from the main tube and it is the only component that can not be replaced. Every other component including the main tube and baffles may be replaced if necessary.
The SMG9-SC is fully user serviceable and is easily maintained. Combustion gasses are contained inside the baffle cones preventing build up from seizing the baffles in the main tube. The end cap lugs and supplied service tool are large enough to support the torque required to remove a stuck cap without damaging the cap or the tool. A unique blast chamber design and supplied service tool eases removal of the baffle stack for cleaning. The service tools are made of Delrin, a high strength engineering plastic that is tough and durable but will not damage machined surfaces or the finish.
The SMG9-SC may be adapted for use on other hosts with the addition of optional mounting caps such as our 3-lug and 5/8-24 threaded mounts.
